As in the last two months I performed another a indexing of the information reported by major websites. It covers mostly request header, HTML and DNS based information of the top 200 sites listed by Alexa and the top 100 German websites. All the information is freely available and only extracted from the website responses!
The detailed results can be found here:
||The HTML header based DNS prefetching is still there and gained another site: German job portal stepstone.de
||IPv6 support did not spread in the last month. Several sites have flapping visibility of their AAAA records.
||adf.ly upgrades from PHP 5.3.8 to 5.4.21.
rtl.de upgrades from Apache 2.2.21 to 2.4.6.
||German health portal imedo.de switched from Mongrel to Apache
|Hiding Server Version
||Porn site xnxx.com stopped reporting usage of PHP 5.3.6
||In 11/2013 conduit.com switched from Cotendo to Akamai CDN.
||German couples portal parship.de seems to have changed hoster and is using BigIP F5 load balancers now.
Note: the website links lead to a history page for the measurements.
All the results listed above are based on a simple scanning script. The results present a snapshot of the websites and a single response only. This is of course not necessarily an indicating for what techniques the site uses in daily operations!
